<p dir="ltr">Hy, My opinion:</p>
<p dir="ltr">ovirt-engine supports configuration of the ovirtmgmt as a non-vm network, untagged. And on top of that nic (bond in your possible specific case) configure all of the VLANs.<br>
If you configure it as a vm network and want to put on the bond other networks too, then you have to configure both the ovirtmgmt and the other ones as tagged VLANs, you cannot mix tagged and untagged in this case. <br>
Or at least it was so that I remained in terms of configuration.<br>
Valid for 3.4 and 3.5, i think.<br>
Can anyone of the net part maintainers confirm?</p>
<p dir="ltr">Other useful configurations, in term of bonding and related considerations (mtu, ecc):<br>
